“First and foremost, all of our thoughts continue to be with the family and friends of Yewri Guillen,” MLB Director of Latin American Operations Jorge Pérez-Diaz said in a statement released by the league. “Yewri’s passing has led to deep sorrow not only for the Washington Nationals franchise, but throughout Major League Baseball in the Dominican Republic and beyond.

“Major League Baseball has commenced an examination into all the facts pertaining to this tragedy, with the full cooperation of the Nationals. Our Medical Director is satisfied that no other players are at risk and proper protocols had been followed to prevent others from being infected. Because the matter is under thorough review, we cannot comment on further details at this time.”
